Marko, This tool is useless for wildcard masking ? I am talking about wildcard, not subnetting. If i need 228.0.0.0 or 230.0.0.0 i would apply a wildcard mask of 00000010.11111111.11111111.11111111 or 2.255.255.255, or a /6 by which i don't mean contiguous bits as in a subnet, but as in 0 bits for wildcard mask use.
The book refers to 226.0.0.0/7 (as to setup both 226 and 227) and sets it up as such. a /7 is 00000001,a /6 is 00000010, a /5 00000101 etc Am i correct or incorrect? Maybe i was not very clear at first, apologies.
